Our NAS test 'system' has migrated to three 42U racks, similar to what you'd find in a datacenter. There are ten servers that attack the target NAS with 120 Hyper-V installations of Windows 7 64-bit, each with a dedicated gigabit Ethernet port. The systems feed to three Extreme Networks X450e-48p switches, and then to a Supermicro SSE-X3348TR top-of-rack switch. The device being tested connects to the Supermicro switch via 1GbE, 10GbE, or 40GbE. The iSCSI and NASPT tests use a single machine connected to the Supermicro switch.

This level of testing wouldn't be possible without the help and support from several companies, many of which have little to do with NAS products. We would like to thank AVADirect, Antec, Corsair, GIGABYTE, Icy Dock, Kingston, LSI, Noctua, Rosewill, Seagate, Thermaltake, and Western Digital for their much-appreciated support.

Intel NASPT

The Intel NAS Performance Toolkit (NASPT) is a file system exerciser and analysis tool designed to enable direct measurement of home network attached storage (NAS) performance. NASPT is designed to emulate the behavior of an actual application, and uses a set of real-world workload traces gathered from typical digital home applications. Traces of high definition video playback and recording, office productivity applications, video rendering/content creation, and more, provide a broad range of application behaviors.
